Ingredients

  • The Cake
  • 2 1/4 cups cake flour
  • 1 1/4 teaspoons baking powder
  • 1/2 teaspoon salt
  • 1/2 cup butter, at room temperature
  • 1 cup granulated sugar
  • 1/2 cup light brown sugar, firmly packed
  • 2 eggs
  • 1/2 teaspoon grated lemon zest
  • 1 cup mashed very ripe banana
  • 1 teaspoon vanilla extract
  • 1/4 cup milk
  • 3/4 cup chopped walnuts
  • The Frosting
  • 1/2 cup butter, at room temperature (1 stick)
  • 4 1/2 cups confectioners' sugar
  • 3/4 teaspoon grated lemon zest
  • 3 -5 tablespoons fresh lemon juice

Method

  • Preheat the oven to 350°F Grease 2 - 9 inch round cake pans and line the bottom of each with a disk of wax paper (see recipe #452719).
  • Sift the flour with the baking powder and salt.
  • In a large mixing bowl, cream the butter with the sugars until light and fluffy. Beat in the eggs, one at a time. Stir in the lemon zest.
  • In a small bowl mix the mashed bananas with the vanilla and milk. Add the banana mixture and the dry ingredients to the butter mixture alternately in 2 or 3 batches and stir until just blended. Fold in the nuts.
  • Divide the batter between the cake pans and spread it out evenly. Bake until a cake tester inserted in the centre comes out clean, 30-35 minutes. Let stand 5 minutes before unmolding onto a wire rack. Peel off the wax paper.
  • For the frosting, cream the butter until smooth, then gradually beat in the sugar. Stir in the lemon zest and enough juice to make a spreadable consistency.
  • Set one of the cake layers on a serving plate. Cover with about one third of the frosting. Top with the second cake layer. Spread the remaining frosting evenly over the top & sides of cake.
